Creating Awareness on Vision and Mission Statements among Employee of Ebonyi State University-Nigeria: A Discourse

The research was carried out to investigate the place of awareness on vision and mission statements among employee of Ebonyi State University-Nigeria; focusing on the implementation and challenges facing the objectives of the cherished statements. A theoretical analysis was adopted to achieve the purpose of the study. The result of the findings indicates that employees in Ebonyi State University are not accustomed with vision and mission statements. The study recommends that the University principal Officers should engage in a campaign on the primary role of these statements and how each employee’s activity may help reposition the organization and achieve greater performance and motivate members concerned.

Ejaculate characteristics of three genotypes of local cocks in the humid tropics

Twenty four (24) adult Nigerian local cocks comprising 8 naked-neck, 8 frizzle and 8 normal were subjected to two ejaculations per week for 14 weeks using the massage technique. Ejaculates were subjected to both physical and chemical evaluations. Results showed that naked- neck and frizzle cocks had higher (P0.05) among the three genotypes. There were also no significant differences in most of the chemical parameters among the genotypes. From these results the naked-neck and frizzle cocks appear superior to normal cocks under the humid tropical environment in semen output and quality..

Energy and exergy evaluation of a 220MW thermal power plant

A component based energy and exergy evaluation was performed on a 220MW thermal power plant in Nigeria. The component based exergy analysis examines and compares the energetic and exergetic performances of each component by identifying the deficiencies of each component. Design and operating data were obtained from Egbin power plant in Nigeria. The result of the analysis showed that the total exergy that was destroyed in the power p lant was 400.015 MW. The major contributors to the exergy destruction in the power plant were the boiler (87%), the three turbines (a combined total of 9%) and the condenser (2 %). The effect of increasing the High Pressure turbine (HPT) inlet temperature at constant boiler pressure incresses the exergy efficiency of the component as well as the second law efficiency of the power plant, thus reducing the exergy destruction of the component. At the variation of environmental or dead state temperature, ther e were no appreciable changes in the values of exergy efficiency of the boiler/steam generator. The outcomes of this work provide the exergy consumption and distribution profile s of the thermal power plant, making it possible to adopt effective energy - saving measures.

Wildlife species diversity indices and seasonal distribution assessment in road-side markets of South-west Nigeria

Wildlife species are under serious exploitation by the rural populace in Nigeria because hu­man beings have understood their ecology. The need to update the existing knowledge of wildlife population is therefore essential. Twenty-three games markets along five Roads in South-west Nigeria were visited to document the wildlife displayed for sale. Two hundred and fifty copies of structured questionnaire were administered using systematic random sampling (odd) method for wildlife species information from market stakeholders. Direct method was counting for species and their numbers. Data generated were analysed through Species Diver­sity Indices Assessment. All emergent species were compared with International Union for Conservation of Nature (IUCN) abundance rating. Road seasonal distribution of the marketed wildlife was determined by percentages, standard deviation, standard error of mean, mean differences, t-test, and tests of significance and Diversity Indices. Results revealed that 69,398 wild animals were displayed. Also more wildlife were sold during rainy than dry seasons. Appropriate recommendations of government sensitization of rural and urban settlers against over-utilization of wildlife resources, encouragement of the public towards animal domesti­cation and others were made

The use of lasers in vitiligo, an overview

Various types of lasers have been demonstrated to be effective in the treatment of vitiligo. The mode of action of these lasers is just as varied as the purpose of intervention. Many clinicians are not aware of the unique opportunity these lasers offer to improve the outcomes of vitiligo treatment. To date, no clear overview exists of the use of lasers in vitiligo treatment. Thus, the aim of this review is to discuss the various types of lasers and provide an overview of the evidence for their efficacy. We found good evidence from a systematic review that the excimer laser is effective, induces repigmentation rates comparable to NB-UVB and has improved outcomes when combined with calcineurin inhibitors. Ablative lasers are commonly used for tissue graft or melanocyte–keratinocyte cell graft transplantation. They provide safe, fast and uniform denudation of the epidermis with propitious repigmentation outcomes. We found conflicting evidence from two systematic reviews regarding the efficacy of fractional ablative lasers for improving outcomes of NB-UVB therapy, a systematic review including only fractional ablative lasers provided evidence for efficacy. Q-switched nanosecond lasers have shown to be safe and effective for inducing depigmentation, although recurrence is common, and most studies were small and retrospective. Despite proven efficacy and safety, laser treatments are relatively expensive and suited for limited body surface areas and selected cases. Each type of laser has benefits and risks associated and should, therefore, be individually chosen based on location, extent, activity and type of vitiligo
